Other diagnostic programs on the Software Selections
CD
The Software Selections CD supplied with your computer also contains
diagnostic programs designed specifically for certain operating
environments (Windows 95, Windows 98, and Windows NT). Because
these versions work with the operating system, they not only test the
hardware, but also analyze certain software components of your computer.
They are especially useful in isolating problems related to the operating
system and device drivers.
CoSession Remote
CoSession availability varies by computer model and country. CoSession is
a remote-control program that can be used by another individual, such as
your in-house administrator, to help diagnose problems with your computer
from a remote location. To use CoSession, this program must be installed
in your computer, and your computer must have a modem or a LAN
connection.
Important
Before attempting to use CoSession, contact IBM or your in-house
administrator for specific instructions on setting up and using the
program.
Recovering from a POST/BIOS update failure
If power to your computer is interrupted while POST/BIOS is being
updated (flash update), your computer might not restart correctly. If this
happens, perform the following procedure to recover:
1. Turn off the computer and any attached devices, such as printers,
monitors, and external drives.
CAUTION:
Do not touch internal components of the computer while the power
is on.
2. Unplug all power cords from electrical outlets and remove the cover.
See “Removing the cover — desktop model” on page 55 or “Removing
the cover — tower model” on page 56, depending on your model.
